Extraction of the nuclear matter incompressibility [ital K][sub [infinity]] from the experimental giant monopole resonance (GMR) data via liquid drop type expansion of compression modulus of finite nuclei [ital K][sub [ital A]] is found to be fraught with uncertainties. Hence a realistic finite range effective interaction is constructed that reproduces the bulk properties of nuclear systems as well as the GMR data in the Thomas-Fermi approximation. The nuclear matter incompressibility calculated with this interaction is found to be 226 MeV. A numerical scheme is also proposed which enables us to extract the various coefficients occurring in the expansion of [ital K][sub [ital A]] employing this effective interaction.
